Answer:
question 20 ) 19.1 feet
question 21) 24 clips
Step-by-step explanation:
<h2><u>Question 20:</u></h2><h3><u>Circumference of a circle </u></h3>formula:
therefore we can find the radius (r) , also include the circumference of 60 feet.
where
2 * 3.14 * r = 60
r =
r = 9.554....
<h3>to find the diameter we can use the formula :</h3><em>diameter = radius * 2</em>
diameter = 9.554 * 2
diameter = 19.108
to 3 sf
<h3><u>diameter = 19.1 feet </u></h3><u />
<h2><u>Question 21</u></h2>large binder clips each cost $ 1.50
amount for purchases is $ 36.00
therefore the number of clips bought can be regarded as (x)
the formula would be :
1.50 * x = 36
x = 36/1.5
<u>x = 24</u>
<u></u>
<h3><u>hence the mom bought 24 binder clips</u></h3>
